Did you reboot and check the bevaviours of Rosegarden etc. after this? FYI. In today's PCs, sound and video chips are usually installed in the chipset on the motherboard, and if we try to use an external video card and/or sound card, the video chip and/or sound chip on the chipset must be disabled in the BIOS setting. If we do not set the video chip and/or sound chip on the chipset to "disabled" in the BIOS, we will have problems using the PC just like you. In addition, sound chips are usually installed in recent external video cards, and if we do not use this chip, we must also set it disable, but this can only be done within the OS that has been booted. In your case, xonar's driver and intel's driver were fighting over the device.
